What is the difference between hunger and appetite?

This is a point you will need to watch with nice discrimination, for the habit of eating purely for sensual gratification is very deeply rooted with most of us. The usual “dessert” of sweet and tempting foods is prepared solely with a view to inducing people to eat after hunger has been satisfied; and all the effects are evil. It is not that pie and cake are unwholesome foods; they are usually perfectly wholesome if eaten to satisfy hunger, and NOT to gratify appetite. If you want pie, cake, pastry or puddings, it is better to begin your meal with them, finishing with the plainer and less tasty foods. You will¬†find, however, that if you eat as directed in the preceding chapters, the plainest food will soon come to taste like kingly fare to you; for your sense of taste, like all your other senses, will become so acute with the general improvement in your condition that you will find new delights in common things. No glutton ever enjoyed a meal like the man who eats for hunger only, who gets the most out of every mouthful, and who stops on the instant that he feels the edge taken from his hunger. The first intimation that hunger is abating is the signal from the sub-conscious mind that it is time to quit.
